The invention relates to an airplane nose landing gear turning performance test bench and a test method, the airplane nose landing gear turning performance test bench comprises a nose landing gear test piece, a rigid support frame and a jacking device, the body of the nose landing gear test piece is fixed on the rigid support frame, an airplane wheel is supported on the jacking device, and a turning mechanism drives the airplane wheel and a top plate at the top end of the jacking device to rotate together through a fixed shaft. The fixed shaft is connected with a loading actuating cylinder, the telescopic end of the loading actuating cylinder is hinged to one end of the fixed shaft, the other end of the loading actuating cylinder is hinged to the supporting frame through a connecting base, the loading actuating cylinder is controlled by a torque loading controller, and when a turning performance test is carried out, a front lifting inner cylinder and an airplane wheel are compressed through a jacking device; the airplane wheels are in a turning state; and according to the turning angle of the airplane wheel, a torque loading executing mechanism is used for applying preset torque to the fixed shaft.

    一种飞机前起落架转弯性能试验台及试验方法,含有前起落架试验件、刚性的支撑架和顶起装置,前起落架试验件的本体固定在刚性的支撑架上,机轮支撑在顶起装置上,转弯机构通过固定轴带动机轮和顶起装置顶端的顶板一起转动,该固定轴连接一个加载作动筒,加载作动筒的伸缩端与固定轴的一端铰接,加载作动筒的另一端通过连接座铰接在支撑架上,该加载作动筒受扭矩加载控制器的控制,进行转弯性能试验时,用顶起装置将前起内筒和机轮压缩,使机轮处于可转弯状态;根据机轮的转弯角度,使用扭矩加载执行机构对固定轴施加预定的扭矩。
